分享PHP函数require()的具体使用技巧
对于使用PHP函数require()包含外部php文件时,只要自身php文件被执行,外部文件的内容就将被包含进该自身php文件,当包含的外部文件发生错误时,系统将给出错误提示,并且停止php文件的执行。
示例:
调用文件config.inc的程序代码:
<ol class="dp-xml"> <li class="alt"><span><span class="tag"><span> ?php </span></span></span></li> <li><span>echo "这就是被调用的内容: 您好 ! " ; </span></li> <li class="alt"> <span class="tag">?></span><span> </span> </li> </ol>
当前脚本example01.php的程序代码:
<ol class="dp-xml"> <li class="alt"><span><span class="tag"><span> ?php </span></span></span></li> <li><span>echo "代码重用的示例: " ; </span></li> <li class="alt"><span>require ( ' config.inc ' ) ; </span></li> <li><span>//调用另外一个文件config.inc,<br>输出config.inc中的内容 </span></li> <li class="alt"> <span>echo "使用require函数实现的." ; </span><span class="tag">?></span><span> </span> </li> </ol>
实例位置:mrsl4example01.php
结果为:代码重用的示例:这就是PHP函数require()被调用的内容:您好!使用require函数实现的。
